Time Resistance review for Propel Upsell & Cross‑sell

Great app to offer add-ons for customers. Works great, easy to use. I used this app as a workaround for custom additional product options(for example "add a gift card to the order" etc.) other similar apps had issues when working with other apps - this app works just great without any troubles. Customer support has solved the few customization issues we had within the same day. Highly recommended
